Response parameter:
Figure 72. Fast Read Multiple Block frame exchange between VCD and M24LR16E-R
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Fast Read Multiple Block command to the end of the M24LR16E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
Inventory Initiated
Before receiving the Inventory Initiated command, the M24LR16E-R must have received an
Initiate or a Fast Initiate command in order to set the Initiate_ flag. If not, the M24LR16E-R
does not answer to the Inventory Initiated command.
On receiving the Inventory Initiated request, the M24LR16E-R runs the anticollision
sequence. The Inventory_flag must be set to 1. The meaning of flags 5 to 8 is given in
Table
The request contains:
The M24LR16E-R does not generate any answer in case of error.
